Re: [docbook-apps] FIXED: [docbook-apps] Processing Xincludes using document() and xml:id (docbook 5)

["Bob Stayton" <bobs@sagehill.net>]

Hi,
id() is an XSLT function (see your local XSLT reference), while xml:id() is 
not.  It has nothing to do with the name of the attribute, only the type of 
the attribute (defined in the schema as attribute type ID). In fact, the 
id() function works fine with xml:id attributes since they are defined as 
type ID.
